What to look for when buying a solar blanket for a saltwater pool

The thickness of the solar pool blanket is a very important factor in meeting your needs. If you intend to retain as much heat as possible and you like your pool to be warm, a thicker solar blanket can do the trick.

When choosing, anywhere between 12-16 mil will ensure that your pool is warm enough. Additionally, depending on your requirements, a thicker blanket may prove to be more beneficial.

If you are looking to reduce your chemical needs or consumption during the swimming season, a 16 mil blue blanket can provide the most excellent protection. This way, your chemicals will be more effective and will last for a while.

Meanwhile, if your aim is to get the warmest water possible, an 8 to 12 mil blanket is the most recommended because of its excellent heating properties.

Apart from these, if you want to have a better chance of penetrating the blanket and warming your pool, you can opt for a transparent solar blanket as it is a good choice for your application.

No matter which thickness or color you choose, one thing is for sure, and that is that you will personally witness a huge difference in chemical requirements and pool water temperature.

In fact, this is why a solar blanket for saltwater pools is a wise investment that usually pays for itself many times over throughout the course of its use.

Do solar pool blankets really work for saltwater pools?

Yes, you can use solar blankets in any type of swimming pool. Whether you intend to use them for fiberglass, salt water, vinyl liners, chlorine, concrete or mineral water, they are safe, effective and work well for what they are designed for.

Solar blankets for pool water are specifically manufactured to maintain the pool's temperature, capturing heat throughout the night and the next day.

It is worth noting that the use of solar pool blankets does not significantly lower the temperature, even on cloudy days. That's how efficiently they work for different types of pools.

In addition to the above list, we have a list of the best swimming pool solar rings to warm your pool.

How long should a pool solar blanket last

The good news is that the construction of a solar blanket for saltwater swimming pools is gradually degrading. You only need to replace it when it starts to peel off, as well as when the air bubbles start to come off.

It's worth noting that most solar blankets are designed to be durable and they can last up to 3 years, although some pool owners prefer to replace them more frequently.


In conclusion, if you want a warm, spa-like pool experience, investing in the best solar blankets for saltwater pools can be one of the most effective, affordable, and convenient solutions.

While such a product cannot heat your above-ground or in-ground pool like a traditional gas heater or electric heater, any type of solar blanket can effectively hold more water and keep more heat in your pool.

Considering the effectiveness, affordable price and longevity of top-notch solar blankets, these products are certainly a very wise and worthwhile investment.
